When the moon hits your eye like a big pizza pie, you may be entitled to compensation. Have YOU been involved in a food-related lunar gravitational mishap that wasn’t your fault? You could be in line for a big payout from the estate of Sir Isaac Newton. Call the hotline now.

Library (archives, research) folk, could you give me your best one liners about Why Cataloguing Matters, please?

Thank you very. #GLAM #archives #rarebooks #metadata 📚
